A fuel cell generator and method of operating same

Abstract: Solid oxide electrolyte fuel cell generators which are operable to reform in-situ a gaseous medium and to utilize the products of the reformation as fuel. A portion of the reformation preferably occurs along an electrochemically inactive extension of each fuel cell.

Speed control apparatus for railroad trains

Abstract: A pair of on-board processing units, operating in parallel, are supplied with input signals representing actual train speed, advance traffic conditions, and selected train parameters. Each unit continuously calculates a maximum train speed from which emergency braking will stop the train within the indicated clear track distance ahead. Each unit also compares the calculated maximum speed with actual train speed and emits a preselected distinctive frequency signal or a d.c. signal as actual speed is less than, or equals, or exceeds maximum speed, respectively. A logic network with parallel filter-rectifier circuit paths passes the unit outputs, if of the preselected frequencies, to a two-input AND gate whose output holds emergency braking released. If a preselected frequency output is absent from either or both units, due to actual speed equaling or exceeding maximum speed or to a fault condition in the apparatus, the corresponding lack of an AND gate output actuates emergency braking. Each processing unit monitors operation of the other unit so that, if a malfunction is detected, the operable unit, when input speed signals are within limits, also emits a second signal of the other unit frequency. This is passed through a separate filter rectifier circuit within the logic network and applied to the second input of the AND gate to maintain train movement.

Mössbauer Effect for Surface Atoms: Iron-57 at the Surface of η A12O3

Abstract: The Mossbauer effect has been observed for Fe57 atoms at the surface of η Al2O3. The Fe57 is trivalent, and the quadrupole splitting found is consistent with a surface location. Anisotropy of thermal vibration relative to the surface is observed.

Dissociative Attachment in CO and NO

Abstract: The electron energy dependences of the cross sections and of the ion kinetic energy distributions have been measured for ${\mathrm{O}}^{\ensuremath{-}}$ production from CO and NO. The present apparatus permits total collection measurements as well as kinetic energy analysis and mass identification of the ions produced. It is shown that in CO two reactions contribute to the single peak in the cross section, whereby carbon atoms are produced in their ground state and in their first excited state ($^{1}D$) respectively. The first reaction is predominant, and known from previous work to have a peak cross section of 2.0 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}19}$ ${\mathrm{cm}}^{2}$. Normalized to this, the second reaction is shown to have a peak cross section of 9.5 \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}21}$ ${\mathrm{cm}}^{2}$. In NO it is shown that ${\mathrm{O}}^{\ensuremath{-}}$ production proceeds exclusively through the reaction $e+\mathrm{NO}\ensuremath{\rightarrow}{\mathrm{O}}^{\ensuremath{-}}+{\mathrm{N}}^{*}$ where $\mathrm{N}*$ is the first excited state ($^{2}D$). No ${\mathrm{O}}^{\ensuremath{-}}$ ions are observed corresponding to the formation of ground state N. Nor is there any evidence for the production of the second excited state of nitrogen, $\mathrm{N}(^{2}P)$, postulated by Dorman to account for the structure in the attachment cross section.
